Acid Peatlands occur in saturated areas that get most of their water from precipitation rather than groundwater. Black spruce and tamarack are some of the only tree species that can survive these very acidic conditions.

Forested Rich Peatlands occur on saturated, moderately acidic peatlands. Common tree species include black spruce, tamarack, northern white-cedar, and balsam fir.

Wet Forest communities are commonly dominated by black ash and northern white-cedar, characterized by seasonally saturated soils connected to groundwater.
